我一直在浏览类似的问题，还没有让这个功能发挥作用。我正在跟踪用户制作嵌入式vimeo视频并插入数据或更新数据的进度。

帖子页面上的JS：

        $.ajax({
        type: \'POST\',
        dataType: \'json\',
        url: ajaxurl,
        data: { 
            \'action\': \'vimeo_progress\',
            \'progress_percent\': progress,
            \'progress_seconds\': seconds,
            \'course_id\': courseID },
        success : function(data) {
            console.log(data); //FOR DEBUG
        },
        error : function(data, textStatus, XMLHttpRequest) {
            console.log(\'updateProgress failed!\'); //FOR DEBUG
            console.log(textStatus); //FOR DEBUG
        }
    });

功能。php

    add_action( \'wp_ajax_nopriv_vimeo_progress\', \'store_vimeo_progress_callback\' );
function store_vimeo_progress_callback() {  
    // don\'t track if user is not logged in
    if ( ! is_user_logged_in() )
        return false;

    $user_id = get_current_user_id();
    $vimeo_percent = sanitize_text_field($_POST[\'progress_percent\']);
    $vimeo_seconds = sanitize_text_field($_POST[\'progress_seconds\']);
    $xxx_course_id = sanitize_text_field($_POST[\'course_id\']);

    $table_name = $wpdb->prefix . "course_video_progress";

    // Run WP query to retrieve user progress
    $row = $wpdb->get_row( $wpdb->prepare("SELECT * FROM $table_name WHERE user_id = %d AND course_id = %d;", $user_id, $xxx_course_id) );

    if ($row) {
        $wpdb->replace( 
            $table_name, 
            array( 
                \'id\' => $row->id,
                \'user_id\' => $user_id, 
                \'course_id\' => $xxx_course_id,
                \'progress_percent\' => $vimeo_percent,
                \'seconds_played\' => $vimeo_seconds
            ), 
            array( 
                \'%d\',
                \'%d\',
                \'%f\', 
                \'%d\' 
            ) 
        );
    } else {
        $wpdb->insert( 
            $table_name, 
            array( 
                \'user_id\' => $user_id, 
                \'course_id\' => $xxx_course_id,
                \'progress_percent\' => $vimeo_percent,
                \'seconds_played\' => $vimeo_seconds
            ), 
            array( 
                \'%d\',
                \'%d\',
                \'%f\', 
                \'%d\' 
            ) 
        );
    }

    $response = array( \'success\' => true, \'data\' => \'hello\' ); //if $data is set
    wp_send_json_success( $response );
    exit;
}

不会将任何数据插入表中，也不会更新任何数据。我确实从回调中获得“成功”，但数据返回为0。

编辑：我刚刚意识到http://localhost/wordpress/wp-admin/admin-ajax.php 返回0，所以可能ajax调用甚至没有找到我的函数，只是返回0？
